Description

Technical Field

[0001] This utility model relates to a packaging machine, specifically to a lid film indentation heating and forming device applied to a double-compartment blister packaging machine. Background Technology

[0002] Currently, double-compartment blister packaging machines are used to separate two similar materials (such as cosmetics or food) into two compartments and package them with an upper cover film (top film) and a lower bottom film (bottom film). When using the double-compartment blister packaging, the indentations on the upper cover film of each compartment are broken to mix the two similar materials. If the indentations on the upper cover film are not obvious, it is difficult to break; if the indentations are too obvious, it affects the seal and can easily lead to minor leaks. Both of these conditions are detrimental to the mixing of packaging materials, thus affecting the quality and effective use of the blister packaging. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned technical deficiencies and provide an easy-breakable lid film indentation heating and forming device that can achieve indentation on packaging lid film and prevent leakage and make the packaging lid film easy to break.

[0004] The objective of this utility model is achieved through the following technical solution: an easy-to-break film-pressing and heating forming device, comprising a frame, a film-supporting roller, a film-pressing mechanism, and a film-traction mechanism. Adjacent film-heating mechanisms and film-forming mechanisms are sequentially mounted on the frame, between the film-pressing mechanism and the film-traction mechanism. The film-heating mechanism includes an upper heating fixing seat and a lower heating fixing seat mounted on the frame. An upper heating power source is mounted on the upper heating fixing seat and connected to the upper heating plate via an upper heat insulation plate. A lower heating power source is mounted on the lower heating fixing seat and connected to the lower heating plate via a lower heat insulation plate. The film-forming mechanism includes a forming cover plate, a forming guide plate, and a forming support seat sequentially arranged on the frame in an upper, middle, and lower configuration. An upper forming mold is mounted under the forming cover plate, a lower forming mold is mounted on the forming guide plate, a forming power source is mounted on the forming support seat, and a cooling plate is mounted on the forming guide plate.

[0005] A molding die holder is mounted on the cooling plate, and this molding die holder is connected to the lower molding die via a locking block. The cover film indentation mechanism includes a support plate mounted on the archway, on which an indentation power source is mounted. The indentation power source is connected to an indentation guide post via an indentation movable plate. The indentation guide post passes through the support plate and is connected to a blade positioning plate. An indentation blade is mounted on the blade positioning plate, and the indentation blade is located below the support plate. A fine-tuning rod is mounted below the blade positioning plate via an indentation base plate, and this fine-tuning rod is connected to the indentation blade.

[0006] The film covering traction mechanism includes a traction bracket mounted on the archway. An upper movable pressure roller and a lower fixed pressure roller are mounted on the traction bracket in an up-and-down rolling configuration. The shaft end of the upper movable pressure roller is connected to a movable pressure roller power source via a movable pressure roller seat. A film pressing fixing base is mounted on the bottom of the traction bracket and on the side of the lower fixed pressure roller. A grooved film pressing fixing block is mounted on the film pressing fixing base. A movable film pressing block is mounted above the grooved film pressing fixing block and is connected to a film pressing power source mounted on the top of the traction bracket. The movable pressure roller seat is mounted on the side of the traction bracket via a guide rail slider.

[0007] With the structure of this utility model, the bottom of the packaging film is first indented by the indentation blade of the indentation mechanism, and then reinforced by the heating mechanism and the forming mechanism. At the same time, the film is pulled by the traction mechanism to prevent the film from falling back. This ensures that the film can be sealed without leakage and is easy to break (can be easily broken with fingers) for subsequent use. This facilitates the mixed and effective use of packaging materials and improves the quality of blister packaging. Attached Figure Description

[0013] Reference Figure 1 , Figure 2As can be seen, the easy-opening blister packaging machine's easy-opening lid film creasing and heating forming device includes a frame 1, a lid film receiving roller 2 (on which a lid film roll 3, made of aluminum foil, is mounted), a lid film creasing mechanism 4, a lid film traction mechanism 8 (and a subsequent lid film guide roller 9). Adjacent lid film heating mechanisms 5 (on the right) and lid film forming mechanisms 6 (on the left) are sequentially mounted on the frame 1, between the lid film creasing mechanism 4 and the lid film traction mechanism 8. The lid film heating mechanism 5 includes an upper heating fixing seat 53 (on the upper side) and a lower heating fixing seat 57 (on the lower side) mounted on the frame 1. An upper heating power source 51 (an upper heating cylinder) is mounted on the upper heating fixing seat 53. A heat source 51 (downward) is connected to an upper heating plate 55 via an upper heat insulation plate 54. A lower heating power source 60 (a lower heating cylinder) is mounted on a lower heating fixing seat 57. The lower heating power source 60 (upward) is connected to a lower heating plate 56 via a lower heat insulation plate 58. The cover film forming mechanism 6 includes a forming cover plate 71, a forming guide plate 64, and a forming support seat 61 (connected by forming guide posts 63) arranged sequentially on the archway 1. An upper forming mold 70 is mounted under the forming cover plate 71, a lower forming mold 69 is mounted on the forming guide plate 64, a forming power source 62 (a forming cylinder) is mounted on the forming support seat 61, and a cooling plate 65 is mounted on the forming guide plate 64. The lower forming mold 69 has several forming grooves for forming reinforcing ribs on the cover film. The indented cover film passes between the upper heating plate 55 and the lower heating plate 56.

[0014] An upper heat-insulating guide post 52 is mounted on the upper heating fixing seat 53, and the upper heat-insulating guide post 52 is connected to the upper heat-insulating plate 54. A lower heat-insulating guide post 59 is mounted on the lower heating fixing seat 57, and the lower heat-insulating guide post 59 is connected to the lower heat-insulating plate 58. A forming mold fixing seat 66 is mounted on the cooling plate 65. The forming mold fixing seat 66 is connected to the forming lower mold 69 through a locking block 68 (and a locking screw 67) to lock and position the forming lower mold. A cover film cursor tracking mechanism 7 is installed on the archway 1, between the cover film forming mechanism 6 and the cover film traction mechanism 8, to facilitate synchronous cursor tracking of the forming positions of the indentations and reinforcing ribs on the cover film to correspond with the bottom film composite.

[0015] After the cover film is unwound from the cover film roll 3 on the cover film receiving roller 2 and indented by the cover film indentation mechanism 4, the indented cover film passes between the upper heating plate 55 and the lower heating plate 56 of the cover film heating mechanism 5. At this time, the upper heating power source 51 and the lower heating power source 60 work to close the upper heating plate 55 and the lower heating plate 56 through the upper heat insulation plate 54 and the lower heat insulation plate 58 respectively, and heat the indented cover film. After the indented cover film is heated, it passes between the upper forming mold 70 and the lower forming mold 69 of the cover film forming mechanism 6. The forming power source 62 works to drive the lower forming mold 69 upward through the forming guide plate 64, and close the lower forming mold 69 with the upper forming mold 70, thereby forming the bottom of the cover film with reinforcing ribs (the reinforcing ribs are several protrusions located on the side of the indentation). At the same time, the lower forming mold 69 is cooled by the cooling plate 65 (filled with cooling water).

[0016] like Figure 1 , Figure 3 As shown, the film indentation mechanism 4 includes a support plate 46 mounted on the archway 1. An indentation power source 48 (an indentation cylinder) is mounted on the support plate 46. The indentation power source 48 (upward) is connected to an indentation guide post 47 via an indentation movable plate 49. The indentation guide post 47 (downward) passes through the support plate 46 and is connected to a blade positioning plate 43. Several indentation blades 44 are mounted on the blade positioning plate 43, and the indentation blades are located below the support plate. A fine-tuning rod 41 is mounted below the blade positioning plate 43 via an indentation base plate 42, and the fine-tuning rod 41 is connected to the indentation blades 44.

[0017] When the film embossing mechanism 4 is working, the film is unwound from the film roll 3 mounted on the film receiving roller 2 and passes through the support plate 46 and the embossing blade 44. At this time, the embossing power source 48 works and drives the embossing guide post 47 and the blade positioning plate 43 to move upward through the embossing movable plate 49, so that the embossing blade 44 can emboss the bottom of the film (press out several embossing strips).

[0018] like Figure 1 , Figure 4As shown, the film traction mechanism 8 includes a traction bracket 87 mounted on the archway 1. An upper movable pressure roller 89 (at the upper position) and a lower fixed pressure roller 90 (at the lower position) are mounted on the traction bracket 87 in an up-and-down rolling configuration. The shaft end of the upper movable pressure roller 89 is connected to a movable pressure roller power source 85 (a movable pressure roller cylinder, mounted on the top of the traction bracket 87) via a movable pressure roller seat 83. A film pressing fixing base 94 is mounted on the bottom of the traction bracket 87 and on the side (front) of the lower fixed pressure roller 90. A film pressing fixing block 93 with a groove 95 is mounted on the film pressing fixing base 94. A film pressing movable block 92 is mounted above the grooved film pressing fixing block 93 and is connected to a film pressing power source 86 (a film pressing cylinder) mounted below the top of the traction bracket 87. The movable pressure roller seat 83 is mounted on the side of the traction bracket 87 via a guide rail slider 82. The lower fixed pressure roller 90 is connected to the main power source (a connected power motor and intermediate transmission assembly 81). The rolling surface of the lower fixed pressure roller 90 has an annular protrusion on both sides and a concave structure in the middle, with the concave part in the middle just able to accommodate the reinforcing ribs at the bottom of the cover film.

[0019] The cover film with indentations and reinforcing ribs passes between the upper movable pressure roller 89 and the lower fixed pressure roller 90, and between the pressure film fixing block 93 with grooves 95 and the pressure film movable block 92. When the cover film traction mechanism 8 is working, when the movable pressure roller power source 85 works, it drives the upper movable pressure roller 89 to move downward through the movable pressure roller seat 83 (along the guide rail slider 82), closing the upper movable pressure roller 89 and the lower fixed pressure roller 90. The cover film with indentations and reinforcing ribs rolls and pulls between the upper movable pressure roller 89 and the lower fixed pressure roller 90. At the same time, the pressure film power source 86 works to raise the pressure film movable block 92, and the cover film passes between the pressure film fixing block 93 with grooves and the pressure film movable block 92 and is conveyed to the left. Furthermore, after being conveyed by the guide roller 9, the bottom of the cover film is turned upwards (i.e., the indentations and reinforcing ribs on the cover film are facing upwards). When the power source 85 of the movable pressure roller operates, it drives the upper movable pressure roller 89 upwards through the movable pressure roller seat 83 (along the guide rail slider 82), causing the upper movable pressure roller 89 to separate from the lower fixed pressure roller 90. At this time, the pressure film power source 86 operates to lower the pressure film movable block 92 to press down the cover film. The reinforcing ribs at the bottom of the cover film are precisely embedded in the groove 95 of the grooved pressure film fixed block 93, effectively preventing the cover film from sliding back to the right. This must be coordinated with the operation of the cover film cursor tracking mechanism 7.
